Merge tag 'x86_sgx_for_6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 sgx updates from Dave Hansen:
"The biggest deal in this series is support for a new hardware feature
that allows enclaves to detect and mitigate single-stepping attacks.
There's also a minor performance tweak and a little piece of the
kmap_atomic() -> kmap_local() transition.
Summary:
- Introduce a new SGX feature (Asynchrounous Exit Notification) for
bare-metal enclaves and KVM guests to mitigate single-step attacks
- Increase batching to speed up enclave release
- Replace kmap/kunmap_atomic() calls"
